Internal thread local defect repairing device and method

Abstract

The invention discloses an internal thread local defect repairing device comprising a positioning disk, a centering assembly, a measuring assembly and a milling cutter assembly. The positioning disk is arranged on a to-be-repaired hole and provided with a position-adjustable centering ring; the centering assembly can be installed on the centering ring and is used for adjusting the concentricity of the centering ring relative to the to-be-repaired hole; the measuring assembly can be installed on the centering ring and is used for measuring the defect position of an inner wall thread of the to-be-repaired hole; and the milling cutter assembly can be installed on the centering ring and is used for milling the defect position. The internal thread local defect repairing device is suitable for repairing the internal thread defect of a screw hole, and it is avoided that because of thread damage, corresponding equipment cannot be used. Besides, the invention further discloses an internal thread local defect repairing method, a centering device, a measuring device and a milling device.

Description

technical field [0001] The invention relates to a thread repairing device, in particular to a repairing device and a repairing method for local defects of internal threads. Background technique [0002] Existing installation methods of equipment or parts are usually connected by screws. For example, the usual way to fix a piece of equipment on a platform is to set threaded holes on the platform, tap internal threads in the threaded holes, and then use screws or The bolt passes through the mounting seat of the equipment, and then connects it with the internal thread, so as to realize the screw fixing of the equipment and the platform. This method is easy to install, can be assembled and disassembled repeatedly, and is easy to use, making it the most common form of installation at present. [0003] However, at some point, due to improper installation or disassembly, the teeth of the screw and the internal thread are not aligned correctly. If the screw is forced into the threa...

Problems solved by technology

[0003] However, at some point, due to improper installation or removal, the teeth of the screw and the internal thread are not aligned correctly. If the screw is forced into the threaded hole, it is easy to squeeze a part of the internal thread, thus making the internal thread Threads and screws cannot be connected together, so that the device cannot be installed on the platform

And because the prior art lacks a device for repairing the internal thread, once some parts of the internal thread are damaged, it will directly cause the equipment to be unusable, which will seriously affect the production work.
